Be it known that we, JosnrdNtonoLsoN 'and WILLrAMHFnnGUsoN, subjects of the `Queen of Great Britain, and residents of the city o fLondon, in the Provinceof Ontario," j Canada, have invented a' certain' new and use- .fnl Vacuum-Campi which vthefcllowing' is a specification. l

, This invention relates to aleen, case, packxq sge,'or the like, and has for its object to projvide device whereby milk, butter, 'and other merchandise nie'y be successfully preserved perfectlysrreet and fresh dnrine,F transportaj-tion or'stonage, and at any time, het particu- 15'giarlyduringthehottestpartcfthesilmmer'and i thecoldestpsrt ofthe winter; and this invention c onsistsof an in-ternelcnse and an exten' v Iitift.,seket, between the 'siges'and'bottom of which a vacuum-chamber is formed, and of the ywhich hold said-case centrally in said jacket, of estoppel' which tightiy closes the mouth oh s 'idjacket, en do fastening or locking attachments whereby the .unjustiebie' or accidenevoided and compietelyl prevented,

in order that these itnprovcxnentsmevhe' better understood, we have iiinstrsted 'inthe aecompnnyingdrewings e can constructed In the drawings, Figure' 1 is n, side elevation .of a. een embodying.our-invention."

The upper reduced portion a of the case I .is fitted tightlyin-and sweated and otherwise incorporated with the neck N. This supports the case I at the upper'end and forms an airtightjoint at this point. The-easel is also supported centreliyin'the jecltetO on the` hollow feet or braces F, which' project upward between theease'l and jacket O and inward 6`c between the` bottoms of said. cese sind said jacket, and these feet F are formed hollow for the purpose of vpreventing` them fromv con-1 ducting the heat or'cold or chnnge'of'tempermure to which the outer jncket D may be subjected across the vacunmchamberAto the4 ca scI, kdesignetes .the vel'vechember, provided with a flange b, by'which said chamber may' be reedilysold'ered'o'r otherwise secured to the 7o jacket O, with an air-tight jeintat ths'point,

and in suchl a, position thatpne endof said chamberl wiljbe inside and vtheA other outside of seid jdcket.I This chamber k is provided with the'vinterior screw-thread, with which a.' 75' screwthreadedplug Z engages, and this ping .is provided with'the longitudinal portor f opening d -designsles e. valve-seat, and e a d1skvalve, which is provided with the stems g, and 8othe latter are guided in the port n and socket inthe chamber 7c and' plug l, respectively.

G. desgnates'a cheinsecured nt one end to ythe cap fr', and to the other endv of this chain an eye L is secured. When constructedas `described, lhe cap r, is removed and the plug Zscrewed. outward, to permit the .valve e to' operate. An airpump or similar device is thenconnected with the chamber k, by which the nir isexxco from the chamber .A the screw-plug Z is screwed down on the valve c to securely hold the latter, and tho cap fr is then screwed on the chamber t', as shown in Fig. 5, to further assist in maintaining an aintght joint at this point. 'ihe castel is then filled with milk or other merchandise and the hollow1 stopper S inserted in the neck N, and this stopper S is inserted in the neck N until the hood C rests on thc funnel 13, as shown in Fig. 2. then adjusted as described, the lower edge ot the hood C will be below the upper rim of the funnel l5, which will avoid and completely prevent rain or other moisture or dust or other impurities from collecting in the funnel i3 or at the junction of the stopper S with the neck N, so that when the stopper is re moved there will bc no danger of said impurities coming in contact with the contents of the case l. The hasp D and oye L are then placed over the staple E and secured by a lock, (not showin) which avoids and com pletely prevents the wrongful or accidental displacement of the stopper S, cap lr, or valve 'lhc advantage of providing thecase I with an outcr jacket t) isthat'y it the latter shouldbe broken into or otherwise accidentally injured the contents of thc easel would be perfectlysafe, and by forming the vacuum-chamber A between said case and said jacket. t) the heat or cold or variation of temperature to whichtheontcr jacket t) may be subjected would have no good conductor to the case I. Uonscgjuently the contents of the case I would be retained or kept atan oven temperature Ato enable the merchandise to be successfully preserved sweet and fresh for any length of said case centrally in said jacket and a stopper, S, substantially as and for the purpose set forth.

2. Acase,l, foi-holding merchandise, t'ormed with an opening for the insertion or removal of the contents, and with a portion, o, sur-r. rounding said opening, said portion, o., being secured to and in combination with a jacket, O, the latter being formed larger in cross section than said case, and provided with a neck, N, and valve, c; a vacuum chamber, A, between'said case and said jacket, feet, F, for supporting the case, centrally in said jacket, and a hollow stopper, S, substantially as and for the purpose set forth.

3. Acase, l, for holdingmerchandise, formed with an opening for the insertion or removal of the contents and with a portion, a., sur rounding said opening, said poi-tierna, being secured to and in combination with a jacket, O, the latter being formed larger in cross section than said case, and provided with a neck, N, and valve, e, a vacuum chamber, A, between said case and said jacket, feet, F, for supporting said caso centrally in said jacket, and a hollowstoppcr, S, provided with a hood, C, substantially as and for the purpose'sct forth.

4. A case, l, for holding merchandise, formed with an opening for the insertion or removal of the contents, and with a portion, a, surrounding said opening, said portion, a', being secured to and in combination with a jacket, t), the latter being formed larger in cross section than said case, and provided with a neck, N, tunnel, 13, and valve, e, a vacuum `chainber, A, between said case andsaid jacket, feet, F, for supporting,r said case centrally in said jacket, and a hollowstopper,S, provided with a hood, C, substantially as and for the purpose set forth. i

5. A case, l, for holding merchandise, formed with an opening for the insertion or removal ot the contents, a jacket, O, provided with a neck, N, to which a staple, E, is secured, a valve, e, 'secured to `said jacket and provided with a cover, r, and an eye, L, secured to said cover by a chain, G, in combination with a hollow stoppoig, provided with a hood, (i, ahasp, l), secured to said hood, and means tor locking said eye, L, and hasp, D, to 'the staple, lil, to prevent the wrongful or accidental displacement of said stopper orvalve,
